' JUNE 22, 193* THE LONDON AERO-MODELS ASSOCIATION (The Society of Model Aeronautical Engineers.) THURSDAY next, the 22nd inst., a discussion will be held on Dr. Hankin's lecture with reference to the best method of experimenting with models for the purpose of attaining soaring flight, and it is hoped that members will bring along wings built up on the flying-fish principle for demonstration purposes. On Thursday, the 29th inst., Mr. F. Handley Page has kindly arranged for Mr. Reynolds, of the Handley Page Research Department, to read a paper before the members at Head quarters, 20, Great Windmill Street, Piccadilly, W., the title of which will be " The Handlev Page Slotted Wing," illus trated by lantern slides. Dr. A. P. Thurston, D.Sc, will preside. Visitors will be welcomed, but, owing to limited accommodation, should notify the Hon. Secretary, A. E. Jones, 48, Narcissus Road, West Hampstead, N.W. 6. Time of lecture, 7.30 p.m. "Flight Golf" Competition for "Flight" Challenge Cup Wimbledon Common, Saturday, July 8, 1922, at 5 p.m. Competitors to assemble at 4.30 p.m. Rules 1. The Competition to be open. 2. Non-members to pay a 2s. 6d. fee for each entry. 3. The prize shall be awarded to the competitor who completes the arranged course in the smallest number of flights. 4. The course to be flown over will be in the form of a pentagon, each side measuring 150 yds. 5. The bases shall be indicated by white flags, attached to which are two cords having a radius of 10 yds. and 20 yds. respectively. 6. The models must start the course from No. 1 base with an R.O.G. flight, and must be in the air at least 10 sees, (two attempts being allowed) or be disqualified. 7. All models must arrive at each base entirely under their own power, the circle of 20 yds. radius precribing the maximum distance that may be " taxied." 8. The direction of course from No. 1 to No. 2 base will be into the wind. 9. A time allowance of 60 mins. will be allowed for rubber- driven models to complete the course, and 75 mins. for models driven by mechanical power—this time to include repairs. 10. The maximum loading allowed will be 8 ozs. per sq. ft., reckoning lifting surface only. 11. After the flight from ground mentioned in Rule 6, all models must continue the course with their landing gear intact or be disqualified. 12. In the event of bad weather conditions prevailing, the judges reserve the right to alter the course or postpone the Competition. 13. All entries for the Competition shall be numbered consecutively as received by the Hon. Competition Secretary, and duplicate numbers issued to the competitors, which must be conspicuously displayed on the entrant's model. 14. Any type of model aircraft is eligible. 15- Competitors must be at the starter's flag, ready to fly, five minutes before 5 p.m. on Saturdav, July 8, 1922, otherwise they will be disqualified. 16.

SIDE-WINDS - REALISING how easy it is to lose that little file for cleaning contact points on magnetos, etc., the Fellows Magneto Co., Ltd., have produced a natty pocket file, which, when ready for the pocket, looks just like a fountain pen. The file is mounted in a handle made of some xylonite substance, while a cap of similar material protects the tool when it is off duty. It can be had in a number of colours, and all you have to do is to send along a postal order for is. bd. to the Fellows Magneto Co., Park Royal, Willesden, N.W. 10. REFERENCE has already been made in these columns to the compensating gear with which the Bristol " Jupiter " and " Lucifer " engines are fitted. This gear ensures that when the cylinders expand, the rockers are shifted in such a way that the actual tappet clearance remains unaltered. In large air-cooled cylinders, such as those of the Bristol engines, the amount of expansion may amount to a good deal, and there is little doubt that the gear assists very materially in the smooth running of the engines. It is of interest to note that this valve compensating gear is the invention of Mr. Raymond Morgan, who holds the patents. The exclusive aircraft rights of the Morgan compensating gear have been acquired by the Bristol Aeroplane Company, of Filton, Bristol, to whom- should be addressed all enquiries for licences to manu facture in connection with aero engines. For all other appli cations, such as to stationary and marine engines, motor cycle and motor-car work, etc., those interested should apply direct to the patentee, Mr. Raymond Morgan, 8, Clifford's Inn, London, E.C. 4.
